Boil the pasta as per package instruction. Chop the veggies. Combine all the veggies and microwave for 2 minutes. Microwaving the vegetables will help to have its color.

In a large skillet with 4 tsp of oil add some Italian seasoning and all purpose flour and fry for a minute. Do not burn or change the color of flour. Add milk slowly, stirring continuously to avoid lumps. Add pepper and salt after thickened.

After the sauce is ready add the cooked pasta and veggies. Add paramesan cheese if needed.
